Description

The pen of losing-proof pen cap

Technical field

The utility model is related to arrive study article field, and in particular to the pen of losing-proof pen cap.

Background technology

Most of writing pen is all pen cap and penholder separation composition currently on the market, this two parts primary structure is all to use Made of plastics, pen cap damage is easily lead to during use, and then cause pen cap that cannot firmly be sleeved on very much penholder Upper (pen cap is difficult to entangle firm at nib in other words), therefore it is exactly homely food to be lost pen cap for writing pen user .Due to the loss of pen cap, protection that pen cap has been lacked in use that many people can select to abandon to that in other words be pen core It is easier to be damaged, reduces the service life of pen core.

Therefore in existing writing pen structure, the bonding strength between pen cap and penholder how is further prevented, is prevented simultaneously Only pen cap loss is one of important topic of research staff in current writing pen structure.

Utility model content

The technical problem to be solved by the utility model is to a kind of pens for preventing pen cap from losing, and mainly solve existing write The technical problems such as the pen cap of word pen and penholder loss.

To achieve these goals, technical solution provided by the utility model is：

The pen of losing-proof pen cap, the pen cap including penholder and with penholder cooperation, the capping of pen cap pass through the upper slot of pen cap side wall The side wall of shaft and pen cap in hole is hinged, and the cover portion in upper slot is provided with bar, and torsional spring is provided in shaft, is turned round Spring one end is contacted with the side wall of pen cap, and the torsional spring other end is contacted with bar, the capping of pen cap and the side wall of pen cap be hinged one Side is provided with pull rod, and pull rod is connect by restricting with the gear in the lower slot on pen cap side wall, gear and penholder outer rim upper hopper chute Interior teeth engagement, the inward flange lower end of pen cap side wall lower ends is expanded to the outside of pen cap, is set in the penholder outer rim below pen cap There is the rubber layer coordinated with pen cap.

Specifically, be the structure being recessed to the longitudinal center line direction of gear in the middle part of the outer gear rim, one end of rope with The middle part connection of gear.

Specifically, the pen cap side wall lower ends can surround rubber layer.

Compared with prior art, the beneficial effects of the utility model are：

The utility model, it is simple in structure, it is easy to operate, it is detached without pen cap with penholder, it is therefore prevented that pen cap is lost, while Pen cap capping of pen cap while being slided on penholder is opened, and adds interest.

Specific embodiment

As shown in Figure 1, 2, the pen of losing-proof pen cap, the pen cap 1 coordinated including penholder 11 and with penholder 11, the capping 2 of pen cap 1 It is hinged by the shaft 6 in the upper slot 4 of 1 side wall of pen cap and the side wall of pen cap 1,2 part of capping in upper slot 4 is provided with Bar 5 is provided with torsional spring 3 in shaft 6, and 3 one end of torsional spring is contacted with the side wall of pen cap 1, and 3 other end of torsional spring is contacted with bar 5, pen The capping 2 of cap 1 is provided with pull rod 13 with the side that the side wall of pen cap 1 is hinged, and pull rod 13 passes through on rope 7 and 1 side wall of pen cap Gear 10 in lower slot 14 connects, and gear 10 is engaged with the teeth 8 in 11 outer rim upper hopper chute 9 of penholder, 1 side wall lower ends of pen cap Inward flange lower end is expanded to the outside of pen cap 1, and the rubber layer 12 coordinated with pen cap 1 is provided in 11 outer rim of penholder of 1 lower section of pen cap.

Be the structure being recessed to the longitudinal center line direction of gear 10 in the middle part of 10 outer rim of gear, restrict 7 one end and tooth The middle part connection of wheel 10.

1 side wall lower ends of pen cap can surround rubber layer 12.

In use, pen cap 1 is slided to the center of penholder 11, gear 10 is engaged with the teeth 8 in sliding slot 9 at this time, gear 8 Winding rope 7, rope 7 so that the capping 2 of pen cap 1 rotates, when cover 2 around the shaft 6 rotate clockwise 90 degree after penholder 11 outer rim with 2 contact of capping at this point, gear 10 is detached with teeth 8, continues to move to pen cap 1, gear 10 slides in sliding slot 9, until pen cap 1 Lower end is contacted with the rubber layer 12 of 11 outer rim of penholder, and rubber layer 12 can prevent pen cap 1 from slipping, and is provided with pen on penholder 11 at this time One end of point can be write at this time beyond capping 2.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
